YARN-GUIDE.

Application filed October 5, 1910.

To all whom it may concern.'

Be it known that I, FnsTUs S. RAND, a

citizen of the United States, 'residing at Providence, in the county ofProvidence and Stateof Rhode Island, have invented certain new anduseful Improvements in Yarn- Gruides, of which the following is aspecilication.

. My invention relates to improvements in threador yarn-guides for useon textile machinery such as spinning-frames, winding machines and otherlike apparatus.

The object of my improvement is to vprovide a self-threading yarn-guidewhich can be threaded with greater convenience and rapidity than theusual pigtail or spiral guiding eye; and which will direct the thread oryarn in its proper course and reduce the tendency to whip out or balloonas it delivers from the supply cop.

The invention is fully described in the following specification,illustratedby the accompanying drawings, in which Figure l is anisometric projection of my improved guide showing it in use forcontrolling the thread delivering from an underneath supply cop; Fig. 2,a plan view of the guide; Fig. 3, a side elevation.

My improved guide A is preferably construct-ed of wire, bent in the formshown in the drawings, and attached to the machine in any suitablemanner. As here illustrated the main portion or shank a is driven intothe bar B which represents a portion of the frame of the machine onwhich the guide is used. The shank ci extends outward to a point abovethe center of the supply cop or bobbin C and is bent at right-angles atb in a horizontal plane to form the ofset portion or cross-bar c. Ashort distance from the bend b the wire is bent again in the same planeat an acute angle, forming the elbow (Z. The inclined portion e of thewire is then bent again at f and continues outward with the portion gextending parallel to and in the same plane with the shank a. At h thewire is bent back in the opposite direction forming a hairpin loop 4withthe side z' substantially parallel to the side g. The side i is alsobent upward slightly from the plane of the shank a; and rests on top ofthe bend b. From this point the wire is bent in a loop j forming withthe cross-bar c the eye 7c through which the thread y leads. From theloop j the wire continues outward with Specification of Letters Patent.

the portion Z extending at a slight angle to the side c'. As beforestated, the side z' rests on top of the bend b at the end of the shanka, but the portion Z is bent upward out of the plane of the side c' soas to provide a clearance where it crosses the bar c and angle portione. Above the bend f t-he wire is bent at fm, and continues in theportion n extending at an angle to the portion g. The portions n and gform a flaring, V-shaped mouth or opening 7) for receiving the threadand guiding it into the loop lc.

The operation of threading the guide is as follows: The thread or yarn yis drawn up from the supply cop C and directed into the opening p, seeFig. 2. As the yarn is drawn into the crotch of the guide to theposition illustrated at w, Fig. 2, the pull on the yarn causes it toride under the bend m and out over the inclined side c of the elbow d,as illustrated at e. Continued pull on the yarn toward the eye 7c willcarry the loop a over the elbow Z and along the crossbar c, under theportion Z and into the eye 7c. As the yarn is drawn up through the eye7c with a rapid draft, in unwinding from the co-p- C, there will be adecided tendency for it to fly out and balloon as illustrated in Fig. l.The direction of movement of the yarn in unwinding is indicated by thearrow w and as it swings around under the guide A the cross-bar cprevents it from whipping out of the eye 7c. The guide as here shownmight be termed left-handed and where it is required to unwind the yarnin the opposite direction a right-handed guide is used; that is, theguide is formed with the cross bar c extending in the opposite directionand the other portions of the wire formed correspondingly. If theleft-handed guide were used in the position illustrated for a copunwinding in the opposite direction from that here shown the yarn wouldbe liable to whip out and catch over the elbow d. The left-handed guide,however, could be adapted for such use by simply turning it over.

It will be seen that my new guide provides for threading the yarn intothe eye or loop 7c by simply drawing it up through the mouth or openingp. In the usual helical form of pigtail guide it is necessary for theoperator to give the yarn a turn under and around the spiral inthreading it through the eye, This not only requires more time and care,but it is also liable to result in forming a loop or bight in the yarnwhich catches on the end of the guide. In other words, unless theoperator is extremely care ful, the yarn is liabley to loop around thewire of the guide, and then when it is taken up under tension, indelivering to the machine, the pull will break it and cause damage andloss of time. In my improved device there is no chance for the formingof a loop or bight in the yarn as the end is drawn up straight from thecop and simply pulled into the crotch p. Furthermore, the yarn isprevented from fiying up and catching on the guide by the cross-bar cwhich directs its course in whirling around the bobbin.

My invention is not limited to the dimensions and exact form here shownand described nor to a guide constructed of wire.

Various modifications might be made in the form and relations of theseveral parts, and other materials used for its construction, withoutdeparting from the spirit or scope of the invention.

bentback at L and continuing in the opposite direction to form a hairpinloop, with the side z' resting on top of the bend b; then bent aroundover the cross-bar 0 to form the loop extending out over the bar c andarm e with a clearance between the overlapping portions; and continuedin an extension n diverging from the portion g to form a V-shapedopening p.

2. A self-threading yarn-guide-consisting of the shank a having anoffset cross-bar c; an elbow (Z at the end of the cross-bar; and adouble loop g, h, z', j, Z extending outward then back and around overthe crossbar c to form the eye k; and terminating in the diverging endn., with an entrance space for the yarn between one side of the loop andthe underlying portions of the guide.

'3. A self threading yarn guide formed with a double hairpin loop havingan underlyingv portion at one end of the loop bent in an elbow with atransverse bar crossing the loop to form an eye le, with the portion ofthe loop adjacent the elbow inclined to the sides thereof and adapted tolead the yarn under one side of the loop and back of the crossbar,substantially as shown and described.

In testimony whereof I aix my signature in presence of two witnesses.
